[0015]
[Problems to be solved by the invention]
Many problems remain in the clamshell-type camera-equipped mobile phone provided with the two display means as described above.
[0016]
The first problem is the problem of changing hands. In the case of a clamshell type mobile phone, when the mobile phone is opened and folded, the vertical direction of the mobile phone is used with the helical portion 106 facing upward as shown in FIGS. Therefore, for example, as shown in FIG. 14, the user closes the mobile phone 100 and shoots the user himself (FIG. 14 (b)), and then shoots another subject (FIG. 14 (a)). When performing various image settings using the one display unit 104, the mobile phone 100 must be opened once after the mobile phone 100 is rotated in the direction rotated 180 degrees up and down.
[0017]
Also, when the mobile phone 100 is opened and used after viewing the incoming call display or the time display of the mail or call displayed on the second display unit 120, the mobile phone 100 is similarly held in a direction rotated up and down 180 degrees. After that, the mobile phone 100 must be opened.
[0018]
Conversely, when the mobile phone 100 is changed from the open state to the closed state, the mobile phone 100 must be held in the opposite direction after being folded. The operation of switching and using the mobile phone is troublesome for the user.
[0019]
A second problem is that the antenna unit 105 provided on the back surface of the first housing 101 occupies a large space. Even when the mobile phone is closed, the size of the second sub-display unit 120 on the rear side is increasing so that more information can be displayed to the user, but as shown in FIG. 11 or FIG. Since the antenna unit 105 occupies a large space on the back surface of the first casing 101, the degree of freedom of arrangement of the second display unit 120 sub-display is limited, and it is not possible to arrange a large so-called sub-display. Impossible.
[0020]
A third problem also concerns the antenna. Since the antenna unit 105 is formed in a convex shape on the back surface of the first housing 101, even if the user attempts to install a shutter button or a sub-display operation button on the back surface, the user may operate the antenna unit 105 with his / her finger. However, there is a problem that it is difficult to perform comfortable operations.
[0021]
The fourth problem is a problem related to miniaturization of a mobile phone. Although there is a demand for miniaturization of the mobile phone as a user's need, in the case of the camera-equipped mobile phone 100, since the camera unit 121 includes a lens and a CCD, a certain thickness is required. When it is arranged at the front end of the first housing 101, the front end requires the thickness of the camera section, so that the front end cannot be made thin. Conversely, when the camera is arranged on the hinge 103 side, when the camera is folded and photographed, the user's hand may obstruct the view of the lens, which is not very practical.
[0022]
The fifth problem relates to camera shake. When the camera unit is arranged at the tip of the first housing 101, the camera unit is located at a position away from the second housing 102 where the user holds the mobile phone when shooting with the mobile phone open. Therefore, it is most susceptible to camera shake of the user. Conversely, when the camera is arranged on the hinge part side, when folding and photographing as described above in the fourth problem, the user's hand may obstruct the view of the lens, which is not very practical.
[0023]

FIG. 9 is a flowchart illustrating the imaging process of the mobile phone 1. In particular, a description will be given of rotating the captured image by 180 degrees when the mobile phone 1 is folded and photographed. Note that the mobile phone 1 can be set to a state in which imaging can be performed by a predetermined operation, that is, a so-called imaging mode, from a folded state or an opened state.
[0096]
First, in step S1, the control unit 40 determines whether or not the mobile phone 1 is folded based on the detection result of the open / close detection unit 49. If it is opened without being folded, the process proceeds to step S2, and if it is folded, the process proceeds to step S8. In step S2, the first backlight 45 is turned on. In step S3, the image data captured from the imaging unit 2 is displayed on the first display unit 5, and the process proceeds to step S4.
[0097]
In step S4, the control unit 40 determines whether the mobile phone 1 is folded based on the detection result of the open / close detection unit 49. If it is open, the process proceeds to step S5. If it is folded, the lighting of the first backlight 45 and the display of the image on the first display unit 5 are stopped, and the process proceeds to step S8.
[0098]
In step S5, the control unit 40 invalidates the input of the second shutter button 23 and detects whether the first shutter button 10 has been pressed. If it is pressed, the process proceeds to step S6, and if it is not pressed, the process proceeds to step S7. In step S6, the image data temporarily stored in the first memory 42 is stored in the second memory 48, and the process proceeds to step S7. In step S7, the control unit 40 determines whether a predetermined operation for ending the imaging mode has been performed by the user. If the operation has been performed, the process ends. If the operation has not been performed, the process returns to step S4. When the imaging mode ends, a predetermined standby screen or the like is displayed on the first and second display units 5 and 20.
[0099]
If it is determined in step S1 that the mobile phone 1 is folded by the control unit 40, the process proceeds to step S8, and the second backlight 46 is turned on. In step S9, the image data captured from the camera unit 21 is displayed on the second display unit 20, and the process proceeds to step S10.
[0100]
In step S10, the control unit 40 determines whether or not the mobile phone 1 is folded based on the detection result of the open / close detection unit 49. If it is open, lighting of the second backlight 46 and image display on the second display unit 20 are stopped, and the process proceeds to step S2. If it is folded, the process proceeds to step S11.
[0101]
In step S11, the control unit 40 detects whether the second shutter button 23 has been pressed. If it is pressed, the process proceeds to step S12, and if it is not pressed, the process proceeds to step S13. In step S12, the image data temporarily stored in the first memory 42, which is rotated by 180 degrees, is stored in the second memory 48, and the process proceeds to step S13.
[0102]
This is because the vertical direction of the camera unit 21 is reversed between the opened state and the folded state of the mobile phone 1. In the folded state, the image data is rotated by 180 degrees at the time of photographing, and then the second memory 48 is rotated. , The image is not turned upside down, regardless of whether the image data is later displayed on the first or second display section 5 or 20. In step S13, the control unit 40 determines whether a predetermined operation for ending the imaging mode has been performed by the user. If the operation has been performed, the process ends, and if not, the process returns to step S10. When the imaging mode ends, a predetermined standby screen or the like is displayed on the first and second display units 5 and 20.
[0103]
As described above, by detecting the opening and closing of the mobile phone 1, the display unit used as a finder at the time of imaging is appropriately switched, so that the user does not need to perform a button operation for switching, and the user does not need to perform switching. This saves time and improves operability and convenience. In addition, when the opening and closing of the mobile phone 1 is detected, the input of the shutter button on the same side as the display unit serving as the finder becomes valid, so that the shutter button can be securely input while looking at the finder, and the operation can be performed. The performance is improved. Further, since the input of the shutter button on the opposite side of the display unit serving as the viewfinder becomes invalid, it is possible to prevent an erroneous operation such as pressing the shutter button by mistake. In addition, when the opening and closing of the mobile phone 1 is detected, the backlight of the display unit serving as a finder is turned on, so that an image is easy to see and visibility is improved. Further, when the image data is taken in a folded state, the image data is rotated by 180 degrees when saving the image data and then saved in the second memory 48. Therefore, when the saved image data is displayed later, the image data is saved. Upside down display can be prevented.
